Nrrn srarss F. O. DEGENER, OF NEW YORK, N. Y.

JB/INTINGr-PRESS.

Specification of Letters Patent No. 22,611, dated January 11, 1859i.

To all whom it may concern:

Be it known that I, FREDERICK O. DEGENER, of the city of New York, inthe county and State of New York, have invented a new and ImprovedlPrinting-Press; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theannexed drawings, making a part of this specification.

In all the figures of the drawings the same letters of reference alwaysdenote the same part of the machine.

Figure l, is a side elevation of my improved printing press the side ofthe frame being removed at the (m, line as illustrated by the red line,in Fig. 2, of the drawings. Fig. 2, is a plan of the press, as I arrangeit; Fig. 3, shows the relative positions of the bed with its form oftypes, the platen with its sheet of paper when at the point of contact,or at the time the impression is being taken.

My invention consists in so arranging and combining an oscillating bedwith an oscillating platen that while each vibrates upon its own centerby means of a third and independent center, is vibrated by a cam so thatthe movement of such cam shall cause the bed and platen alternately toopen and close; when open the sheet is to be placed upon the platen, butwhen closed the impression is given upon the sheet which had previouslybeen placed upon the platen. This movement is produced by a simpleeccentric cam, or crank or some equivalent motion causing both the bedand platen, simultaneously, one with the other, to reciprocate in theirmotions harmoniously; each being controlled in its relations to theother by the center, or shaft which unites the two at the lower endwhile each separately revolves upon its own independent center. Also inso arranging the distribution of ink (L), and the inking rollers thatthe form shall in its transit from one position to the other pass underthe inking rollers and thus the form be inked immediately before itarrives at the point of Contact; that is, the point of impression. Andfurther my invention consists in so arranging a frisket or gripperswhich shall receive their motion from the movement of the bed or platen,(either or both of them), in manner to be herein described.

To enable those skilled in such like arts,

to make and use my invention I will describe its construction andoperation.

In the drawings is the frame of the press, so formed and arranged as toaccommodate the various parts of the machine for Y' their differentmanipulations.

(B) is a shaft, (being the main or driving shaft), having the drivingpinion (C) upon it, which gears into (D), upon the shaft (E), at theother end of the shaft is placed a pulley The toothed wheel (D), isarranged so that the crank or eccentric position will admit of theattachment of the eccentric center to the connecting rod (Gr) on oneside of the press, while (II) occupies a like relation upon the otherside of the press. These connecting rods or shackle-bars are connectedeach to the other by the rods (I).

The form-bed (J) revolves in its reciprocating motions upon itsstationary shaft (K), the bed having a flanch upon either side, so thatthe shaft (K) may pass through and yet remain in its proper position.Upon each side of the bed are the distributing rollers (L).

'Ihe platen (M) is jointed to the crank or arms (N) which cranks areloose upon the shaft (O). These shafts (K and O) being located at thetwo opposite ends of the press.

On either side of the press the platen arms are atliXed and will beknown as (P, P,); these arms project from the platen at right angleswith the shaft (O) the opposite ends thereof being connected with armson the bed by the movable shaft (Q) which passes through the arms (R,R,) and project from the inner side of the bed (J), that is from theflanches (a).

(S, S) are ink rollers, the journals of which work in the stationaryframe.

To the outer end of one of the arms (It, It) a cam (U) is attached. Thiscam consists of a slot (b) passing entirely through so as to form anOpen hollow cam; in this a pin projecting from the crank (see C indrawings) is prepared so as to fit in such groove this crank (CZ) isfitted to the end of a shaft (e). To this shaft the ends of two bars (f,f,) are attached, and these bars close upon the sheet like a frisket toretain t-he placed sheet in its proper position upon the platen andthere retain it, draw it from the form, and then relieve the same sothat the neXt sheet may be placed in the place itself had occupied.

Operation: Motion being properly given to the shaft (B) the connectingrods will perform their oliice so that When the bed and platen rotate intheir reciprocating motion Will advance toward and recede from oneanother in the proper time. The bed with its form of types passing underthe inking rollers so as to ink the form as it passes t-o and fro. As inthe motions, the platen approaches a horizontal position, the bars (f,f,) are in a vertical position; being governed by the open cam (U) andcrank (ci). In this arrangement the bars, springs or other contrivance;or frisket if desired or some equivalent thing may be used as a guide tolay the sheet against and there retain it until the proper time forrelief. As the bed and platen approach the point of impression, thefrisket or its substitute are by the same means brought upon the sheetupon the platen so as to hold the sheet in its place until its propertime for relief. rIhe form of types and sheet of paper to be printedcome in contact as they approach the point of impression, as shown atFig. 3. The printed sheet Will at the proper time be removed from theplaten; and another sheet Will be placed in the position Which itspredecessor had occupied; when its succes sor Will lill its place and soon continuously.

By this construction the flat surface or bed and platen press isrendered extremely simple and efficient; and the press may be Workedrapidly Without danger to its Working parts.

After thus carefully describing my invention I Will remark that myprincipal discovery relates to the bed and platen, so

that the action of one Will control the action of the other, and theunited movements of either or both of them shall control the action ofthe frisket or some other instrument Which Will hold the sheet in itsplace upon the platen from the time it is placed on the platen, until ithas been printed and Withdrawn from the form, so that its succeedingsheet shall receive the next impression.

Having thus fully described my invention and its application to use, IWill state that I do not claim separately an oscillating bed nor anoscillating platen for these have been previously used. Nor do I claimseparately an oscillating frisket, but

lVhat I do claim as my invention and desire to secure by Letters Patent,is

l. So arranging or hanging an oscillating bed with an oscillatingplaten, in such manner that the motion of one, Will control the actionof the other so that by their forward movement they shall close, andgive an impression; and upon their reverse movement the form shall beinked, and the platen be brought into the proper position, necessary forthe reception of the sheet ,-and thus alternate from one of thesepositions to the other.

2. I claim the arrangement of an oscillating bed and platen asdescribed, with the cam to cause the frisket to assume the desiredposition so as to hold the sheet of paper While it is being conveyedfrom one position to the other, all of which is herein described.
